Here's your weekly round-up of the biggest video game news stories from the past seven days, including Square Enix's huge Final Fantasy 15 live-stream event, news regarding what to expect from Mass Effect: Andromeda's politically-charged new story and the launch of Nintendo's Miitomo.

Square Enix has confirmed reports that highly-anticipated RPG Final Fantasy 15 will be released worldwide for PS4 and Xbox One on 30 September. The announcement was made at the Final Fantasy 15 Uncovered live event held in Los Angeles in the early hours of 31 March.

Bioware's highly-anticipated sci-fi RPG Mass Effect: Andromeda, will depict humanity colonising the Andromeda Galaxy. That's according to a leaked survey from developers Bioware, posted on a video game forum.

The survey suggests that the plot will differ hugely to that of the first three Mass Effect games (2007-2012), in which humanity and other alien races of the Milky Way were confronted by a race of ancient mechanical lifeforms called the Reapers.

Nintendo's social networking app Miitomo is now available for download in the UK, US and wider Europe. The app is the first product of Nintendo's partnership with mobile developer DeNA, which it announced roughly in mid-March 2015.
